Journal ArticleDOI
Three-phase rectifiers with suboptimal current injection and improved efficiency
TL;DR: In this paper, three-phase diode bridge rectifiers that apply sub-optimal current injection and active resistance emulation are analyzed for continuous and discontinuous conduction modes. But the results are not applicable to the case of continuous conduction.
Journal ArticleDOI
Low-Noise Isolated Digital Shunt for Precision Class-D Power Amplifiers
TL;DR: In this paper, a half-bridge inductor was designed to reduce the signal to noise ratio (SNR) of an isolated current measurement at the output of a halfbridge.
Proceedings ArticleDOI
Planar inverted-F antenna design for a fully implantable mechanical circulatory support system
TL;DR: The design of an implantable Planar Inverted-F Antenna for the use with a TET system, which operates in the MedRadio band at 403.5 MHz and which is suitable for implantation depths of more than 20 mm and the critical design parameters as well as the influence of the human tissue on the antenna design are discussed in detail.
Proceedings ArticleDOI
Comparative Evaluation of ARCP and Three-Level TCM Soft-Switching Bridge-Legs for High-Frequency SiC Converter Systems
TL;DR: In this paper , a comparative evaluation of the 3L-TCM and active Resonant Commutated Pole (ARCP) bridge-legs is presented for the realization of 2.2 kW (per phase), 800 V DC bridge leg with latest-generation 1200 V and 650 V SiC MOSFETs.
Proceedings ArticleDOI
Design and Experimental Analysis of a Selfbearing Double-Stator Linear-Rotary Actuator
TL;DR: In this paper, a selfbearing double-stator (SBDS) LiRA with integrated magnetic bearings is presented, which employs concentrically arranged linear and rotary stators placed inside and outside a cylindrically shaped mover.
